  [Screen Time Refactoring] Add API to show system Screen Time blocking view or blurred view instead

Reviewed by Aditya Keerthi.

Add API to give clients the choice to show WebKit's system Screen Time blocking view
or blur the web content.
- If true, WebKit will show the Screen Time blocking view.
- If false, WebKit shows a blurred view of the web content, which isn't interact-able
nor can any web content be actually visible.

Add three new API tests for this bit, as well as checking if the appropriate views are
added in the view hierarchy.

In WKWebView, WKSTVisualEffectView is a subclass NSVisualEffectView and we
override mouseDown among other events. This is so when the blurred view is up,
we do not allow navigation to links via clicking links
that are "underneath" the blurred view or other interactions such as clicking on
an input text field.
In other words, this is to make the web content with the blurred view
not interact-able.
